Internal drive removal and installation - ThinkCentre A50, S50

This section provides information and instructions for removing and installing internal drives.

Internal drives are devices that your computer uses to read and store data. Your computer does not have the capacity to install additional drives but you might want to install higher capacity drives or a different type of drive to enable your computer to read other types of media. Some of the different drives available for your computer are:

  • Parallel Advanced Technology Attachment (ATA) Integrated Drive Electronics (IDE) hard disk drive
  • Serial ATA IDE hard disk drive
  • Tape drives
  • CD-ROM, CD-RW, or DVD-ROM optical drives
  • Diskette and other removable media drives

When you install an internal drive, it is important to note the type of drive that you are installing.

The following illustrations show a parallel ATA IDE hard disk drive and a serial ATA IDE hard disk drive.
